Hi Selim
I am very interested in a self build in Bristol,I am a wood worker by trade and have developed a method of framing using small diametre round wood (larch and sweet chestnut up to 12 inch) as well as having some general building experinece.
I would idealy invest with other people on a site which could then be divided up into self build plots and communal areas.
Its putting the cart before the horse but you'd be welcome to come down the yard and see the framing tecnique i'm using and have a general chat on self build, like wise anyone else interested in methods of house construction.
Look forward to hearing from you Tom
